The accumulated practical and theoretical competence in the food hygiene area, as well as knowledge of current trends of the food base broadening, allow us to analyze the risks associated with novel food obtained of insects. <b>The purpose</b> of the research was to analyze the microbiological and parasitological risk of novel food sources obtained with the use of insects, suggest the effective risk management measures. <b>Material and methods</b>. The analytical part of the work included literature search, collection of information and statistical materials published in domestic and foreign scientific editions. The search was carried out using the Google Academy retrieval system and electronic databases (PubMed, MEDLINE, EMBASE, Scopus, Web of Science, eLIBRARY), mainly in the last 25 years, using the keywords: Hermetia illucens, Tenebrio molitor, Acheta domesticus, insects, parasite, nematode, pathogen, cysts. <b>Results</b>. Based on the published materials' analysis, a systematization of microbiological and parasitological factors potentially capable of colonizing edible insects has been carried out. There were identified representatives of 24 groups of pathogenic and 18 opportunistic microorganisms and helminths related to microbial and parasitic pathogens, the spread of which is significantly influenced by inappropriate conditions of feeding and keeping insects. As there are currently no veterinary requirements for insect breeding and farming conditions, contamination of end products with infectious and parasitic pathogens can vary over a very wide range. <b>Conclusion</b>. The use of native insect biomass carries certain risks associated with its microbial and parasitic contamination, and the development of measures to prevent them requires significant resources. The possibility of deep processing of such raw materials can be considered as one of the solutions to mitigate these risks. For use in the food industry, insects should be subjected to processing similar to that currently used for soybean seeds, which includes separation of protein (entomoprotein), fat and chitin fractions, each of which would have an independent use. Thus, at present, insects should be considered as a source of novel food ingredients, first of all, complete protein of animal origin.</p>","PeriodicalId":23652,"journal":{"name":"Voprosy pitaniia","volume":"93 3","pages":"41-49"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141724525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was carried out on 37 growing male Wistar rats (initial body weight of 45±5 g) divided into 4 groups. Animals of the 1st (control) and the 2nd groups received a complete semi-synthetic diet (CSSD) (20% protein, 10% fat, 58% carbohydrates in the form of starch, 384 kcal/100 g) for 92 days. The levels of all vitamins and mineral elements in the rats' diets were adequate for growing rats. Rats of the 3rd and the 4th groups were fed a high-calorie, high-fat high-carbohydrate diet (HFHCD) (20% protein, 28% fat, 2% cholesterol, 18% carbohydrates in the form of starch, 20% sucrose, 511 kcal/100 g). Animals of groups 2 and 4 were subjected to daily 90-minute immobilization. The concentration of vitamins A (retinol and retinol palmitate) and E (α-tocopherol) in the blood serum and liver were determined by high-performance liquid chromatography, vitamins B1 and B2 in the liver and urine, as well as riboflavin in the blood serum and 4-pyridoxic acid (4-PA) in urine were determined by fluorimetric methods. Biochemical parameters of blood serum were determined on a biochemical analyzer; the total content of fat, triglycerides (TG) and cholesterol (CH) was determined in the liver. <b>Results</b>.

The need for ω-3 PUFAs is especially high during periods of rapid growth (the first years of life and adolescence). ω-3 PUFAs play an important role in the anatomical and functional development of the brain, affecting the maturation and functioning of neurons, participating in the processes of neurogenesis, migration, synaptogenesis, and neurotransmission. The results of clinical studies on the effect of ω-3 PUFAs on the cognitive functions of healthy children and patients with attention deficit hyperactivity disorder are contradictory, which requ ires further research. PUFAs are substrates for the synthesis of bioactive compounds and take part in the control of acute and chronic inflammation, and also have a regulatory effect on immune cells. ω-3 PUFAs supplementation decreases the frequency and duration of acute respiratory viral infections in children.

Our studies have shown that soy proteins in the diet improve vascular reactivity in rats with a high-salt dietary load and renal dysfunction. We hypothesized that the introduction of soy proteins into a high-fat diet (HFD) can prevent or reduce vascular dysfunction. &lt;b&gt;The aim&lt;/b&gt; of the study was to test the hypothesis about the possible protective effect of soy protein isolate on endothelium-dependent dilation of the mesenteric arteries of male Wistar rats receiving an excess amount of fat in the diet. &lt;b&gt;Material and methods&lt;/b&gt;. The study used 3 groups of 20 rats, weighing 220-240 g. The HFD group received a diet containing 50% fat (by calorie value) and 20% casein, HFD + Soy group received a diet containing 50% fat and 20% soy isolate SUPRO-760, the control group - a standard casein diet. After 8 weeks, the responses of mesenteric arteries precontracted with phenylephrine to acetylcholine (ACh) were studied in the absence and with the use of NO synthase (L-NAME), cyclooxygenase (indomethacin), BKCa and Kv channel (tetraethylammonium) blockers, using microphoto- and video recording of the vessel diameter in vivo. &lt;b&gt;Results&lt;/b&gt;. Compared with the standard diet, visceral fat mass increased by 54.6% in rats fed HFD and by 25.9% in rats fed HFD + Soy (p&lt;0.01). In the HFD + Soy group, the increase in blood pressure was less than in the HFD group (p&lt;0.01). Consumption of HFD + Soy prevented disorders typical of HFD, reducing glycemia and insulin resistance, normalizing lipid metabolism (p&lt;0.05). Evaluation of the functional state of the mesenteric arteries (in vivo) showed that in the HFD + Soy group the amplitude of dilation on ACh remained close to the control group, whereas in the HFD group the suppression of ACh-induced relaxation was observed (by 19.8% (p&lt;0.01). After blockade of NO synthase by incubation with L-NAME the magnitude of vasodilation on ACh decreased (p&lt;0.001) in the HFD group by 47.0±7.4%, in the HFD + Soy group - by 68.2±6.6% and in the control group - by 68.9±5.6%.

The introduction of soy proteins into a HFD prevents the development of impairs characteristic of MS: it reduces visceral obesity, improves the state of carbohydrate and lipid metabolism, and has a hypotensive effect. The protective effect of soy proteins on vascular reactivity in rats with excessive fat consumption was confirmed: the introduction of soy protein isolate into the diet leads to the prevention of endothelial dysfunction characteristic of HFD, preventing the disruption of NO-dependent vasodilation mechanisms.

Immediately after running, the animals were placed in metabolic cages to collect daily urine. At the end of the experiment, the content of corticosterone, the activity of catalase, indicators of protein, lipid and mineral metabolism, indexes of the liver functional state and antioxidant defense system parameters were analyzed in the blood serum; the level of prostaglandin E2 and dopamine were determined in daily urine. <b>Results</b>. Physiological tests (CRAR, OF) showed that weekly exercise increased anxiety in laboratory animals. The FFI introduction into the diet led to normalization of the assessed parameters (EPM). As a result of 36-day consumption of FFI against the background of physical loads, a significant decrease by 22% in the main stress marker, corticosterone, was revealed in the blood of rats, as well as significant increase by 23% in the stress inhibitor - prostaglandin E2 urinary excretion, compared with animals of the Run group to the level not differed from the indicators of the control animals. There were no differences in endurance performance between the Run and Run-FFI groups on the results of the exhaustive exercise. Consumption of FFI prevented the formation of excess ammonia, significantly reducing the level of urea in the blood and normalizing its excretion to control levels in the urine, which was increased in the Run group by 19%. <b>Conclusion</b>. The results obtained demonstrated the adaptogenic properties of the developed FFI in response to stress caused by weekly moderate and acute exhaustive physical activity.

Obesity is considered as an inflammation of low intensity, which is accompanied by the manifestation of various metabolic complications and a disturbance of intestinal homeostasis. IAP is one of the participants in the mechanism of the macroorganism protection against inflammatory and infectious processes, carrying out enzymatic detoxification of bacterial lipopolysaccharide (the trigger of the inflammatory process). Deficiency of IAP activity contributes to the risk of obesity, inflammatory diseases. <b>The objective</b> of the research was to summarize the current understanding of the role of IAP involved in the molecular mechanism of diet-induced obesity and to evaluate the impact of dietary components - fats and dietary fiber on IAP activity. <b>Material and methods</b>. A literature search on the role of IAP in the development of obesity was carried out using PubMed, Scopus, Web of Science, Google Scholar, ResearchGate, RSCI databases. <b>Results</b>. IAP prevents the development of the inflammatory process by participating in the detoxification of toxic bacterial products, limiting the translocation of pathogenic bacteria from the intestine to various tissues and organs of the macroorganism. The enzyme maintains the integrity of the intestinal barrier, influencing the synthesis and proper localization of tight junction's proteins between intestinal epithelial cells, promotes changes in the composition of the microbiota, decreasing pathogenic bacteria and increasing the population of the community of beneficial microorganisms. IAP is involved in the regulation of fatty acid absorption and influences on the adipogenesis. Monitoring the activity of IAP present in human stool can predict the early development of such complications associated with obesity as metabolic syndrome and diabetes mellitus, Some nutrients modulate IAP activity. Depending on the amount, type, composition of fats and the duration of their consumption, either an increase or decrease in the IAP activity are observed, while dietary fibers stimulate the activity of the enzyme. <b>Conclusion</b>. IAP activity can be considered as an early predictor of the risk of obesity. Deficiency of IAP activity contributes to the development of obesity caused by high-fat diet. The high activity of the enzyme contributes to the support of intestinal homeostasis and limits transepithelial movement of bacteria, weakening the inflammatory process induced by lipopolysaccharides, the excess concentration of which is detected in obesity. Stimulating enzyme activity through dietary intervention reduces the risk of obesity and metabolic complications.</p>","PeriodicalId":23652,"journal":{"name":"Voprosy pitaniia","volume":"93 1","pages":"44-60"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140332077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
